HOWARD K. KING, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO CHAMBERS BROTHERS COMPANY, A CORPORATION OF PENNSYLVANIA.

SLIP-SHEE'IING MACHINE.

Application filed January 22, 1913.

T all whom t may concern Be it known that I, HOWARD K. KING, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia, State of Pennsylvania, have invented a new and useful Slip-Sheeting Machine, of which the following is a specification.

My invention relates to improvements in slip sheeting machines, and is an improvement or modification of the means shown in my Patent No. 1,094,908, dated Apr. 28, 1914, 1n that case advantage was taken of the different thicknesses of the printed sheets and the slip sheets, in operating a caliper device which controlled pneumatically operated devices.

rlhe present invention takes advantage of the difference in width or length of the slip sheets and the printed sheets, whereby the shorter or narrower sheets escape a detector, and the longer or wider sheets encounter the same. asthe case may be.

Referring to the drawings, which illustrate merely by way of example, suitable means for effecting my invention, Figure 1 is a plan view. Fig. 2 is a fragmentary section on line 2 2 of Fig. 1. Fig. is an end elevation of the switch and actuating mechanism on an enlarged scale. Fig. 4 is a fragmentary view, part elevation and part section of some of the parts shown in Fig. 3 on a reduced scale. Fig. 5 is a fragmentary view in elevation of the latch and actuating means therefor. Fig. 6 is an end elel vation of the valve tripping means. Fig. 7

is a section on line 7-7 of Fig. G. Fig. 8 is a view similar to Fig. 7 with the exception that the cam and cam shaft are omitted and the valve trip is in a different position.

Serial No. 743,428.

the stationary framework is pivoted at 82 the lever 17 actuated at its free end by the cam 18 engaging with roller 19 and the lever is controlled by the compression spring 20. On the same axis 82 is pivotally mounted the lever 21 adjustably secured to lever 17 by means of the set-screws 22, which operate through lugs 23 on lever 21 embracingy the short end of lever 17. @n the free end of lever 21 is mounted the chambered body 24. This valve chamber is provided with the cylinder 25 in which operates the valve piston 26 between conductors 27 andz 28, 27 being connected with the source of air pres sure and 28 being connected with a pneumatic diaphragm. 28 is also adapted to be separated from and connected with the eX- haust port 29, by said piston. The valve piston 26 is normally controlled by the spring 30. The trip lever 31 is pivoted at 32 between the lugs 33 projecting downwardly from the chambered body 24. One end of this lever 31 is adapted normally to rest against the lug or projection 34, and the valve piston 26 is adapted to rest upon the` trip lever between the point of its pivot support and the other or free end of said lever. rlhe guide plate 35 upon which the sheet 36 is adapted to travel, see Figs. 7, 8 and 9, is provided with the slot 37 adapted to register with the outer end 38 of lever 31.

Operation: The operation of this device is as follows: The cam 18 is caused to rotatein certain relation with the delivery of sheets along the guide plate The rotation of the cam 18 causes the oscillation of the lever 17, and consequently the lever 21, with a short dwell in one position and a long dwell in the other position, as the lever 21 is oscillated, or moved upwardly and downwardly. It will be understood that the trip lever 31, supports, on one side of its pivotal axis, the valve piston 26. Theend of said trip lever on the other side of its pivotal aXis normally rests against the lug 34. So long as the trip lever 31 meets with no obstruction in the downward movement of-.the chambered body 24, the parts all' remain in the same relative positions as shown in Fig. 7. It will be noted that in the upward and downward movement of the chambered bodyv 24, the trip lever 31 passes below the .level of the guide plate 35, and, when there is no obstruction on said guide plate, the lever passes into and out of the slot 37, without in any way affecting the movement of the several parts. iVhen however, a sheet, such as 36, is of sutlicient length or width to extend over the slot 37 as indicated by the dotted line 36, in Fig. 9, and also as indicated in Fig. 8, the trip lever 31 moving downwardly with the chambered body 24, will en# counter the sheet in said downward move- .ment and will be held stationary during the balance of the downward movement of the head 39. lVithin the diaphragm head 39.

is secured the diaphragm 40, plate 41 secured thereto and piston rod 42 secured to the plate. Piston rod 42 is pivotally secured at 43 to lever 44. Lever 44 is secured to the shaft 45'which has operative relationship with the shaft 46 upon which are mounted the switch elements 47. The outer end oflever 44 iscontrolled b v the spring 48. In Fig.` 4. the diaphragm and diaphragm plate are shown in the depressed position, that is, with air pressure in the diaphragm head 39 consequently the piston rod 42 is shown in the depressed position and the switch elements in the position with the points 49 out of the channels 50 of the roller 51. When pressure isv relieved from diaphragm chamber 39 and the latch 52 is disconnected from the end 53 of lever 44 the spring 48 tends to return the lever into the position shown in Fig. 3, in which the ends 49 of the' switch elements'rest in the channels of roller 51.

As already explained, in said Patent No. 1,094,908, the switching elements 47 in one position serve to deflect the sheets, as the)7 pass between drop and feed rollers 51 and 51 respectively, to one pile and in another position permit the sheets to be delivered to'another pile. For example, in arrangement shown inf Fig. 2, the switching elements are in such position that the points 49 are withdrawn from the channels of the lroller 51so that the sheet is delivered between roller 5l and switching elements 47 to pile 54 by means of suitable nippers, 55 on endless chains 56 already described in my said patent. Whereas when the switching elements are shifted into position shown in Fig. 3 with' points 49 resting in the channel 50 the sheets will be carried over the top of the switching elements 47 along guides 57 to be engaged by the grippers 58 on the endless chain 59 and be delivered to the pile (il). The latch member 52 is pivotally secured at 61 and is normally controlled by the spring 62. As above indicated, it is adapted to engage the outer end 53 of lever 44. The outer or latching end 53 of said lever is inclined on its lower side and is adapted to wipe the arc shaped surface 63 which lies in an arc having a center at 45 when in engagement with the end 53 so that when the end of lever 44 is moved downwardly to its. lowest position it passes the extension of the are surface and at the end of which the latch 52 is forced above the point 53 b v its spring 62 into engagement as shown in Fig. 4. The projection 65 is provided for preventing the lever 52 from being actuated past the point 53 of lever 44. The latch lever 52 is also provided with a bifurcated wing or projections 65 which are adapted to be engaged bythe bosses 66 on the arms 67 so that as the arms rotate, the bosses. in the properperiods of the machines operation. disengage the latch from the arm 44. to permit the same to return to normal or spring actuated position.

The purpose of this latching mechanism is to maintain the lever 44 in the depressed position, as shown in Fig. 4. until the sheet has cleared the point 49. as it passes around roller 51. The arms 67, carrying the bosses 66, have suitable relative rotation, willi respect to the other operations of the machine. in order to release the latch, after the sheet has cleared, as above pointed out.

Operative relationship between shaft 45 and shaft 46 is secured b v means of universal gear mechanism comprising pinions 69, 70, 71 and 72. mounted in the ring or housing 73 as shown in Fig. 13. Pinions 69 and 71 are keyed to shafts 45 and 46 respectively, while pinions 70 and 72 are mounted on'studs connected with the ring or housing 73. In the housing or ring 72 is also mounted the bolt 76, having the operating pin or handle 77. The bracket 79 is connected with the stationary framework of the machine and is recessed to receive the bolts 76 as clearly shown in Figs. 12 and 13. Secured to pinion 72 is the collar 74. similarly recessed at to receive the other end of the bolt 76. The spring 78. see Fig. 15. is provided to coperate with handle 77 to maintain the bolt in either position. that is, in the position shown in Figs. 12 and 13, where it is engaged with the bracket 79, or in the elevated position engaging withthe collar 74.

The operation is as follows: Then the bolt is in engagement with the bracket 79 the ring or housing 73 is prevented from turning, whereupon the pinions rotate and Liconsa the driving shaft 45 transmits motion through the pinions and 72 to pinion 71 thus rocking the shaft 4G in directions opposite to the movements of shaft 4-5. lVhen, on the other hand, bolt 76 engages in recess o'f collar 74, the pinions are all locked with the housing, and hence the two shafts are practicallylocked together and rotate together. One of the advantages of such an arrangement is this, that where for any reason it is desired to shift the relative directions of the sheets, for example, if with the two shafts locked together the larger sheets Were going over switch elements 47 f: and the smaller sheets were going around the roller 51 and it was desired to change this order it would be necessary simply to bolt the housing to the bracket 79 and the distribution would be reversed.
